The deep passage seemed bottomless. The three of them looked at each other, but no one asked to withdraw.

Nalan Yu walked cautiously at the front, and Shi Bao and Lan Xin also cheered up and walked in bravely.

The three of them walked for a while, and Shi Bao discovered that there seemed to be murals of mechas painted on the dark walls, which looked very majestic.

She suddenly became energetic, holding a torch and watching with interest. Lan Xin also saw that there was no danger around, and looked at the mecha murals on the wall casually.

Water is dripping from the top of the cave, probably because Mount Jia is shrouded in clouds and mist all day long, and the natural air humidity is relatively high.

Although the water has damaged the appearance of some murals, you can barely see clearly. The paintings on them probably depict the history of mechas from hundreds of years ago.

Mecha originated in the north of the Tianlong Empire. It was mainly built by a blacksmith in the north for a noble.

The nobleman failed to get the approval of the contract beast, so he had to buy back the mecha at a high price, although he still failed in the family martial arts competition.

But her steel armor was an eye-opener for everyone. At that time, an elder of the family saw an opportunity and dedicated it to the emperor.

In order to arm those mid-level military forces with average qualifications, the emperor ordered the blacksmith to make thousands of mechas.

Unexpectedly, the newly born mecha warriors actually played a huge role on the battlefield. As soon as they came on the field, they acted as a surprise force and defeated the Mammoth Army of the Kingdom of the Sun.

The woolly mammoth is an elephant with average qualifications but a large size. It was trained by the Kingdom of the Sun to be a soldier's mount, and it also became the ace of the Sun Kingdom's army.

From then on, the mecha legion of the Tianlong Empire also stepped onto the stage of history.

Unfortunately, with the development of the times, the strength of the human race has greatly increased, but the update of mecha technology has been too slow, and gradually it has lost its original deterrent power.

On the contrary, the high-level Yuan Beast, as a contracted beast of the human race, greatly enhances the strength of the human race after being armored.

And the legions composed of high-level Yuan Beasts have also become the backbone of the empire. The Golden Lion Legion on land, the Azure Dragon Legion in the sky, the Black Tortoise Legion in the sea...

A senior commander even declared: "The strongest armor is the beast armor, and the mecha is just a pile of scrap metal at best..."

Although the mecha warriors were angry, what the senior commander said was also true.

Indeed, the cost of mechas is much higher than that of ordinary armor, but the benefits are far less than that of Yuan beast armor, and it is not even as useful as the leather made from Yuan beast hides...

It wasn't until mecha researchers developed large-scale mechas and living mechas that mechas were allowed to continue to stay on the battlefield and even be used in some advanced fields.

The mural at the back was actually interrupted, which left people a little unfinished...

The three people who came here are all mecha enthusiasts, otherwise they wouldn't be here.

The three of them particularly hope to find the writings of the legendary romance master, and even some information on mecha research. In this way, they may be able to develop better mechas and improve the combat effectiveness of the mecha warriors.

But what is strange is that except for the occasional sound of water drops and the strange sound of wind in the cave, there is no life here.

After reading a volume of murals, Lan Xin was about to look elsewhere to see if there was anything new, but found that the murals had started from scratch again.

At present, they can only bite the bullet and move forward. As they walk, they find that the end of this mural is the beginning of the history of mechas just now.

At this time, Nalanyu suddenly exclaimed with some surprise: "We seem to have been standing still..."

Shi Bao's words were also trembling: "We have just been to this place."

Lan Xin looked at the mural she had just seen on the wall and felt a little panicked. Could it be that they had entered a new maze?

The maze is the most annoying thing, especially in such a dark and depressing environment.

The three of them stood there and discussed for a while. Lan Xin suggested: "Maybe we can look for another way out and see if there is any other way out."

They continued to move forward, but this time they slowed down. Nalanyu also held a torch on the wall and carefully observed some corners to see if there were any clues.

After walking for a long time, I still see the familiar road, the familiar murals, and even the place where the water dripped.

Now the three of them were a little irritable. Lan Xin looked at the mural in front of her and felt inexplicably confused.

She also felt that the three of them had been trapped in place by some kind of formation, but she clearly heard a gust of wind just now.

Usually where there is a rumor, there will be another exit, but she was a little unsure.

In order to prove her idea, Lan Xin also said to the other two people: "I just heard the news, and it seems that there is another way out."

Shi Bao was feeling upset and she had no patience. When she heard Lan Xin say this, she quickly responded: "Then let's leave quickly."

But Nalan Yu on the side said confidently: "I brought the compass made by my sister. Come with me. I will definitely find a way out."

As she spoke, Nalan Yu's mechanical eyes shot out a green light, and a compass appeared in front of her. It seemed that she had indeed been prepared.

But Lan Xin had just activated the Wind Spell, and she believed in her own skills even more. Because she came to this world, she actually didn't quite believe in these technological products.

After all, the time-traveling and reborn female Zunguo has appeared, and her ideas have also undergone tremendous changes.

Compass, in this fantasy world, is not that convincing.

Shibao looked at Nalan Yu, then at Lan Xin, and finally said: "I believe in Lan Pipi, and I will go with Lan Pipi."

But Nalan Yu insisted: "You have to believe me. The compass made by my sister is very useful here. Last time we successfully brought back a mecha here."

But Lan Xin secretly complained: "Haha, if it helps, you walked through the maze for a long time? And you were seriously injured by a mecha?"

But after all, they were teammates now, so it was hard for her to directly say the hurtful words in her heart.

Lan Xin was very happy that Shi Bao believed in her, but at this time she had to say something nice: "Sister Yu, either we divide into two teams. You take the compass and I go according to my feeling. Once which team finds a way out, immediately send out the message

Signal the other party.”

When Nalan Yu heard this, she had no choice but to nod her head in agreement. She took a breath and said, "Okay, please be safe."

So the three people divided into two teams and began to take the path they thought was right.

Nalan Yu took the compass and started it, but she still felt a little uncomfortable: "You two little brats, what do you know? Haha, wait until you come back crying and beg me..."

However, Lan Xin and Shi Bao moved forward according to their own feelings.

Originally, the three of them were walking together, but slowly, because they kept observing the surrounding environment and it was relatively dark, no one noticed that there were fewer people around them.

Lan Xin and Shi Bao went one way, and Nalan Yu took the compass and went another way.

After an unknown amount of time, the three of them discovered that they were still familiar with the murals, familiar water drops, and familiar scenes. Unconsciously, they were no longer three people...

What on earth is going on?
